00., or BELLEVILLE, ILLIiIoIs, A CORPORATION or DELAWARE REMOVABLE GRATE FOR STOVES i 7 Application filed July 9,

-' vide an im roved su ort for the rate bars of a stove, which support may be detached and dlsconnected from the grate bars so as to permit the grate bars to drop to the ash receptacle from which the said grate bars may be removed without the necessity of removing the ,top of the stove.

Other objects will appear from the following description, reference being made to the drawing in which Fig. 1 is a plan view of the base ofthe stove embodying the present invention.

Figs. 2 and 3 are cross sectional views on the lines 22 and 3-3 of Fig. 1, respectively, looking in the directions designated by the arrows at said lines.

The stove base shown comprises walls 1 inclining upwardly from a base flange 2 to integral connection with an approximately inwardly extended horizontal wall or flange 3. A long door opening 4 is formed through the front wall 1 to afford access to the ash receptacle5. The wall or flange 3 is formed with an upwardly extended flange 6 on its upper side for engagement with the lower end of the wall forming the stove proper (not shown).

Under the wallor flange at one end a supporting bracket is secured. This supporting bracket comprises a plate 7. having an inwardly extended portion 8 from the inner end of which a flange 9 extends upwardly. The plate 8 is. secured to the stove base by bolts 10 and the flange 9 is formed with roundon the adjacent ends of-the grate sections 13.

The opposite end of one of the grate sections 13 is formed with a long axial member 1 1 which projects through and is pivotally supported in a hole 15 in the opposite end wall 1 of the base. The other grate bar sec- 1928. Serial No. 291,215.

'tion has an axial projection 16 which is pivotally supported on a downwardly and upwardly curved arm 17 projecting from the side 1801? a supporting member 19. A lug 16 projecting downwardly and inwardly 5 from the walls 3 and l pre'vents displacement of the projection'16 from the-arm 17, and the wall llimits endwise movement of the grate section in the direction of the member 14:.

The supporting member 19 has a projection 7 20 on one end which is seated ina correspondingly shaped notch in one side of the wall or flange 3; and on its other end-the supporting member19 has a flange 21 seated'in a correspondingly shaped notch in one side of 65. the wall'or flange 3 and is securedthcreto by a stove bolt 22. When mounted in this way one of the grate sections is pivotally supported and held from longitudinal movement in one direction by the arm 17 and the other grate bar is held in proper relationship therewith by contact of the side 18 with the axial pivot member 14. The pivot member 14 projects beyond the stove base a suficient distance for engagement with a cranlzor lever 2'5 whereby it may be rocked. The two grate bar sections are geared together by segmental racks 23' so that they will be rocked in unison.

' In the event either of the grate bar sections becomes burned out or otherwise damaged so so that it is necessary to remove it and substitute another, such removal and substitution may readily be effected without taking apart or removing the upper portion cat the stove (not shown). removing the bolt 22 and then removing the support 19 permitting the endof the grate section of which the axial pivot 16 is a part to drop to the bottom of the ash receptacle. 7 This grate bar sect-ion may then be manipulated to release the arm 12 from the bracket 8 and turned to angular position and removed through the door opening .41:

The other grate bar section may be re-.

moved and another substituted by sliding the 7 This is accomplished by 8;

grate bar section may be turned around in the stove base until the end of the axial pivot member 14 extends toward the door opening 4, in which position this grate bar section may be easily withdrawn.

Then other grate bar sections may be inserted into'the stove base through the door opening 4 and mounted with their pivots 12 on the support 9, the axial pivot member 1% of one grate section extended through the hole 15, as shown and described, and the axial pivot member 16 of the other grate section mounted upon the arm 17, after which the bolt 22 is replaced andtightened.

A grate bar structure or" this type and of the dimensions andrelationship described is quite'an advance over those which require the upper portion of the stoveproper to beremoved in order t'o'ma'ke repairs and replace ments in the grate. The construction and arrangement may" be varied within equivalent limits without departure tromthe nature and principle of the invention.

I do-not restrict myself unessentially in these or other'respects, but what'l claim and desire to secure by Letters Patent is 2- 1. In a-stove, a stove base having an ash receptacle provided with a door opening through oneside, a bearing member attached to one endwallof the base within the ash receptacle, a pair of grate sections each having one end supported 'for rocking move- -ments on said bearingmember and one of said grate sections being held from en'dwise 'mo'vement in a direction away from said hearing member by the opposite end wall of the base, a bearing supporting the opposite end of said one grate section from said-bearing member, an element mounted on said base and supporting said bearing and being removable with said bearing to'permit the end of the grate section supported thereby to drop to position for withdrawal through said door opening, an axial member in connection with the other grate section journaled in the end wall of said base adjacent to said bearing and constructed for engagement by a rocker lever, and means for rocking said first grate section by said'last mentioned grate section.

2. Ina stove, a base havin 'a door open ingthrough one side, a bracket attached to one end of said base, a pair of grate sections 'each having one-end supportdfor rocking movements in said bracket and one of said grate sectionsbeing'held from endwise' movement in a direction away from said bracket by the opposite endwall'of the base, a bearing element supporting the opposite end of one gratesection'from said firstnamed en d andb'eingremovable topermit the end of said'gr'ate section that is supported thereby tojdrop' to position for withdrawal through said-door -opening, and an axial memberin connection with the'other grate section journaked in the endwa'll of said base that holds said first named grate section from endwise movement as aforesaid.

3. In a stove, a base having a door opening through one side, a bracket attached to one end of said base, a pair of grate sections each having one end supported for rocking movements on said bracket and one of said grate sections being held from endwise movement in a direction away from said bracket by the opposite end wall of the base, a bearing element supporting the opposite end of one grate section from said first named end and being removable to permit the end of said grate section thatis supported thereby to drop to position for withdrawal through said door opening, an axial member in connection with the other grate section journaled in the end wall of said base that holds said first named grate sect1on from endwise movement as aforesaid and having its end exposed and constructed for engagement by a rocker lever, and means for rocking said first named grate section by said last mentioned grate section.

4. In a stove, upwardly inclined side and end walls forming the side and end walls of a base, an inwardly extended flange integrally united with the upper edges -ofsaid-walls,a bracket attached to one end of said end walls,

a pair of grate sections eachhaving one end supported for rocking movements on said bracket, a bearingelement mounted on said flange supporting the opposite end of one of said grate sections and being"removable=to permitthe grate section thatis supported me sections and being: removable to permit the J end of said grate section that is supported therebyto'drop to positionfor withdrawal through said door opening, meansfor'preventing displacement ofsaid grate section all;
